摘要
１９９３年７－８月间在浙江省临安县泉口实验场桃茶间作园内的试验结果表明：与纯茶园比较，密植园光强减少６０％，稀植园减少４０％。０ｃｍ地温日较差，纯茶园比稀植园大７．１℃，比密植园大１１．１℃；空气水气压和相对湿度，晴天密植园比稀棺园大２．０ｈＰａ和８％，阴天大１．１ｈＰａ和６％，密植园与纯茶园离地１２０ｃｍ高处的空气湿度差，白昼为４．０ｈＰａ－６．２ｈＰａ和７％－９％，夜间为０．４ｈＰａ－２．８ｈＰａ和２％－５％；离地１２０ｃｍ高处的日平均风速，纯茶园为０．４９ｍ·３￣（－１），稀茶园为０．９ｍ·ｓ￣（－１），密植园为０．４ｍ·ｓ￣（－１）。
This paper reports the microclimate observation results of tea garden intercropping with or without peach trees at Qiankou farm, Ninan county,Zhejiang Province.Compared tea gar-den's illuminance that of intercropped gardens’decreases 40%. About soil temperature differences at 0 cm,the tea garden's is 7.1℃ higher than that of the thinner' and 11.1℃ higher than that of dense. Comparing water-vapour pressure and relative air humidities, the dense's increases 2.0 hPa and 8%in a shiny day and 1.1 hPa and 6% in a cloudy day respectively. The air humidity differ-ences between the dense intercropped garden and the pure tea garden at 120 cm above the ground,are 4.0 hPa-6.2 hPa 7%-9%in daytime,and 0.4 hPa-2. 8 hPa,2%-5%in the night respec-tively.The average daily wind speeds are 0.49 m·8￣(-1) in the tea garden,0.19 m·s￣(-1) in the thin-ner's and 0.14m·S￣(-1) in the dense's.
